Who has not suffered the rupture of the damn lock tab of these junk RJ45 plugs (as that designed them lost his fingers and a billion flea itch). When this happens you must then purchase a new cable, sometimes along several tens of meters and above must be put in place. The solution is to have a short cable that can easily change when it happens. This IS the solution. Do not forget that the Ethernet cable is faster, more reliable and more secure than WiFi.
